To precise my main questions: Is anybody aware of any other (relevant) soft- or hardware which uses the type 'm' for MIDI ? or more general: Is somewhere out there and does know of an (un)official MIDI-Protocol definition for OSC Synthax (like TUIO is for sensoric data) ? Because if someone wants to send MIDI over OSC, I would prefer to be compatible and not proprietary. Since I did not find anything convincing (see addendum) and in favor for existing implementations dropping type 'm', I propose to define the MIDI protocol not with a type 'm' in REST-style (even MIDI is stateful): "/midi" ",iii" status data1 data2 or shorter 12 bytes instead of 28 bytes: "/m" ",i" (status<<16 + data1<<8 + data2) and for sysex to be complete: "/midi/sysex" ",b" [n*data] short: "/ms" ",b" [n*data] > Although [packOSC] and [oscformat] do not directly support the m tag, > you could still cook your own format using 'b' (blob) type and four > bytes.

Anyhow I have to implement it on the other side in the escher-microcontroller also. Addendum: a) Why MIDI is better than OSC is stated here :-) https://www.midi.org/articles/white-paper-comparison-of-midi-and-osc b) There is on midi.org a lot of specifications and recommendations for a various set of transport of MIDI data: Serial MIDI Ports, 5 Pin DIN, Wireless MIDI, RTP MIDI, USB MIDI, OSX MIDI, iOS MIDI, Web MIDI, Bluetooth MIDI but none for OSC mfG Winfried -- -- - ao.Univ.Prof. DI Winfried Ritsch - [email protected] - http://iem.at/ritsch - Institut fuer Elektronische Musik und Akustik - University of Music and Dramatic Art Graz - Tel. ++43-316-389-3510 (3170) Fax ++43-316-389-3171 -- _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list
